Consider the following code sample

def sum(a: int, b: int):
  return a + b

def wrap(*args, **kwargs):
  # delegate to sum
  return sum(*args, **kwargs)

The code works well except that type hint is lost. It's very common in Python to use *args, **kwargs to implement delegation pattern. It would be great to have a way to keep the type hint while using them, but I don't know if it is possible and how.
